While Grand Central station is a must see in itself there is quite a quirky feature that people should experience.
The archway outside the Grand Central Oyster Bar and Restaurant creates a neat trick with sound. Simply stand in one corner of arch and whisper something into the wall. A friend who is standing diagonally across from you in the other corner will hear you as if you were standing next to them.
